S/UNI-PDH

The S/UNI-PDH is a second generation enhancement to the PM7321 PLPP. In addition to all of the functionality previously provided by the PM7321 - the S/UNI-PDH provides an integrated E3 framer (both G.751 and G.832), supports E3 trail trace. The part is packaged in an 84 Pin PLCC (Backwards compatible with the PM7321) and also in a 14 by 14mm 100 Pin PQFP. Note that both the PLPP and S/UNI-PDH chips interface seamlessly with the PM4341A and PM6341 T1/E1 singlechip framer/LIU chips for use in T1/E1 ATM UNI's.
